1. Korinther 5:7 Kommentar

In this chapter the apostle, I. Blames them for their indulgence in the case of the incestuous person, and orders him to be excommunicated, and delivered to Satan (Co1 5:1-6). II. He exhorts them to Christian purity, by purging out the old leaven (Co1 5:7, Co1 5:8). And, III. Directs them to shun even the common conversation of Christians who were guilty of any notorious and flagitious wickedness (Co1 5:9 to the end).

Here the apostle exhorts them to purity, by purging out the old leaven. In this observe, I. The advice itself, addressed either, 1. To the church in general; and so purging out the old leaven, that they might be a new lump, refers to the putting away from themselves that wicked person, Co1 5:13. Note, Christian churches should be pure and holy, and not bear such corrupt and scandalous members. They are to be unleavened, and should endure no such heterogeneous mixture to sour and corrupt them. Or, 2. To each particular member of the church. And so it implies that they should purge themselves from all impurity of heart and life, especially from this kind of wickedness, to which the Corinthians were addicted to a proverb. See the argument at the beginning. This old leaven was in a particular manner to be purged out, that they might become a new lump. Note, Christians should be careful to keep themselves clean, as well as purge polluted members out of their society. And they should especially avoid the sins to which they themselves were once most addicted, and the reigning vices of the places and the people where they live. They were also to purge themselves from malice and wickedness - all ill-will and mischievous subtlety. This is leaven that sours the mind to a great degree. It is not improbable that this was intended as a check to some who gloried in the scandalous behaviour of the offender, both out of pride and pique. Note, Christians should be careful to keep free from malice and mischief. Love is the very essence and life of the Christian religion. It is the fairest image of God, for God is love (Jo1 4:16), and therefore it is no wonder if it be the greatest beauty and ornament of a Christian. But malice is murder in its principles: He that hates his brother is a murderer (Jo1 3:15), he bears the image and proclaims him the offspring of him who was a murderer from the beginning, Joh 8:44. How hateful should every thing be to a Christian that looks like malice and mischief. II. The reason with which this advice is enforced: For Christ our passover is sacrificed for us, Co1 5:7. This is the great doctrine of the gospel. The Jews, after they had killed the passover, kept the feast of unleavened bread. So must we; not for seven days only, but all our days. We should die with our Saviour to sin, be planted into the likeness of his death by mortifying sin, and into the likeness of his resurrection by rising again to newness of life, and that internal and external. We must have new hearts and new lives. Note, The whole life of a Christian must be a feast of unleavened bread. His common conversation and his religious performances must be holy. He must purge out the old leaven, and keep the feast of unleavened bread of sincerity and truth. He must be without guilt in his conduct towards God and man. And the more there is of sincerity in our own profession, the less shall we censure that of others. Note, On the whole, The sacrifice of our Redeemer is the strongest argument with a gracious heart for purity and sincerity. How sincere a regard did he show to our welfare, in dying for us! and how terrible a proof was his death of the detestable nature of sin, and God's displeasure against it! Heinous evil, that could not be expiated but with the blood of the Son of God! And shall a Christian love the murderer of his Lord? God forbid.

INTRODUCTION TO 1 CORINTHIANS 5 In this chapter the apostle blames the Corinthians for conniving at a sin committed by one of their members; declares what he was determined to do, and what should be done by them in this case; and in general advises to shun conversation with wicked men; in Co1 5:1 mention is made of the sin committed by one among themselves, and which was publicly known, and commonly talked of; and which in general was fornication, and particularly incest, a man lying with his father's wife; and which is aggravated by its being what was not named, or could not be named among any virtuous persons among the Gentiles without offence: and yet the members of this church, at least the majority of them, were unconcerned at it, and were so far from mourning over it, and taking any step to remove the person from them that had done it, that they were swelled with pride, and gloried on account of their gifts, and perhaps on account of this man, who had committed the iniquity, Co1 5:2. This affair being related to the apostle, though at a distance; and he well knowing all things concerning it, as though he was present, resolved what should be done in this case by himself, Co1 5:3 and that was to deliver the man to Satan, in the name, and with the power and authority of Christ, when the members of this church were gathered together, and his Spirit with them; the end of which was for the destruction of the man's body, and the salvation of his soul, Co1 5:4 and then the apostle returns to blame them for their glorying in men, and in external gifts, and pleading these as a reason why the man should be continued, and not removed from them; not considering the danger they were exposed to, and which he illustrates by the simile of leaven, a little of which affects the whole lump: suggesting thereby the danger they were in by continuing such a wicked person among them, Co1 5:6 wherefore pursuing, the same metaphor, taken from the Jewish passover, he exhorts to remove from them the man that had sinned, as the Jews at the passover removed the leaven out of their houses; that so they might appear to be a church renewed, and purged, and clear of leaven, keeping the true and spiritual passover, which they were under obligation to do, since Christ, the antitype of the passover, was sacrificed for them, Co1 5:7 wherefore it became them to keep the feast of the Lord's supper; and indeed, to have the whole course of their conversation so ordered, as to avoid sin and sinners, and to behave in truth and uprightness, Co1 5:8 when the apostle goes on to put them in mind of what he had formerly written unto them, as suitable to the present case, which was, that they should not keep company with wicked men, particularly with fornicators, such as this man, though in a more heinous manner, Co1 5:9 and explains what was his meaning; not that they were to have no manner of conversation with persons of such a character, and of such like evil characters, in things of a civil nature, for then there would be no living in the world, Co1 5:10. But his sense was, that they should keep no company with persons guilty of the sins mentioned, who bore the name of Christian brethren, and were members of the same church state with them, from whose communion they ought to be removed; and indeed, so much familiarity with them should not be indulged, as even to eat with them, Co1 5:11. The reason of this difference, which he made between wicked men, who were not members of the church, and those that were, is because he had nothing to do, nor they neither, with them that were without the church, as it was their business only to take cognizance of them that were within, Co1 5:12 but neither of them had anything to do, to judge and censure those that did not belong to the church, but should leave them to God, the righteous Judge; and then closes all, Co1 5:13 with what he had chiefly in view throughout the whole chapter, and that is, that they would remove from their communion the wicked person who had been guilty of the sin first mentioned.

Purge out therefore the old leaven,.... Meaning either the incestuous person, whose crime might well be compared to sour "leaven", and be called old because of his long continuance in it; whom the apostle would have removed from them; this is properly the act of excommunication, which that church was to perform, as a quite distinct thing from what the apostle himself determined to do. The allusion is to the strict search the Jews made (g), just before their passover after leaven, to purge their houses of it, that none of it might remain when their feast began; which they made by the light of a lamp, on the night of the fourteenth of the month Nisan, in every secret place, hole, and corner of the house: or this may be an exhortation to the church in general with respect to themselves, as well as this man, to relinquish their old course of sinning, to "put off concerning the former conversation the old man", Eph 4:22 the same with the old leaven here; it being usual with the Jews (h) to call the vitiosity and corruption of nature , "leaven in the lump"; of which say (i), "the evil imagination of a man, as leaven the lump, enters into his bowels little, little, (very little at first,) but afterwards it increases in him, until his whole body is mixed with it.'' That ye may be a new lump; that they might appear to be what they professed to be, new men, new creatures in Christ, by their walking in newness of life; and by removing that wicked person, they would be as the apostles were, when Judas was gone from them, all clean through the word of Christ: as ye are unleavened; at least professed to be. They were without the leaven of sin; not without the being of sin in their hearts, nor without the commission of it, more or less, in their lives; but were justified from it by the righteousness of Christ, and had the new creature formed in their souls, or that which was born of God in them, that sinned not. The apostle compares the true believers of this church to the unleavened bread eaten at the passover, for the grace of their hearts, and the simplicity of their lives; as he does the incestuous man to the old leaven, that was to be searched for, and cast out at the feast: for even Christ our passover is sacrificed for us. This is observed, to show the pertinency of the similes of leaven and unleavened, the apostle had made use of; and to make some further improvement of them, for the use, comfort, and instruction of this church; saying, that Christ is "our passover", the Christians' passover; the Jewish passover was a type of Christ; wherefore Moses kept it by faith, in the faith of the Messiah that was to come; see Heb 11:28 as it was instituted in commemoration of the deliverance of the Israelites from Egypt, so likewise to prefigure Christ, and the redemption of his people by him. The Jews have a saying (k), "that in the month Nisan they were redeemed, and in the month Nisan they will be redeemed;'' which was the month in which the passover was kept; and for the confirmation of which, they mention the following texts, Mic 7:15. There is an agreement between the passover, and Christ, in the sacrifice itself, and the qualities of it; it was a "lamb", as Christ is the "Lamb" of God, of his appointing and providing, and fitly so called, for his innocence and harmlessness, his meekness, humility, and patience; it was a lamb "without blemish", as Christ is, without spot and blemish, without the spot of original sin, or blemish of any actual transgression: it was a male, as Christ is the son or man, the head of the body, and the "firstborn" among many brethren; it was a male of the first year; in which it might prefigure Christ in the flower of his age, arrived at man's estate, and having had experience of a variety of sorrows and afflictions. There is also some likeness between them in the separation and slaying of it. The passover lamb was to be "taken out from the sheep, or from the goats"; as Christ's human nature was chosen out from among the people, and, in God's eternal counsel and covenant, separated from the rest of the individuals of human nature, and taken into a federal union with the Son of God, and preordained before the foundation of the world, to be the Lamb slain; it was also wonderfully formed by the Holy Ghost in the virgin's womb, and separated and preserved from the infection of sin; and in his life and conversation here on earth, he was separated from sinners, from being like them, and is now made higher than the heavens. This lamb was kept up from the "tenth" of the month, to the "fourteenth", before it was killed; which might typify preservation of Christ, in his infancy, from the malice of Herod, and, in his riper years, from the designs of the Jews upon him, until his time was come; and it is to be observed, that there was much such a space of time between his entrance into Jerusalem, and his sufferings and death; see Joh 12:11. The lamb was "slain", so the Prince of life was killed; and "between the two evenings", as Christ was in the end of the world, in the last days, in the decline of time, of the age of the world, and even of the time of the day, about the "ninth" hour, or three o'clock in the afternoon, the time between the two evenings; the first evening beginning at noon as soon as the sun began to decline, the other upon the setting of it. There is likewise a comparison of these together to be observed, in the dressing and eating of it. The passover lamb was not to be eaten "raw nor sodden"; so Christ is to be eaten not in a carnal, but in a spiritual way, by faith; it was to be "roast with fire", denoting the painful sufferings of Christ on the cross, and the fire of divine wrath that fell upon him; it was to be eaten "whole", as a whole Christ is to be received by faith, in his person, and in all his offices, grace, and righteousness; not a "bone" of it was to be "broken", which was fulfilled in Christ, Joh 19:36 it was to be eaten "with unleavened bread", which is spiritualized by the apostle in the next verse; and also with "bitter herbs", expressive of the hard bondage and severe afflictions, with which the lives of the Israelites were made bitter in Egypt; and significative of the persecutions and trials that such must expect, who live godly and by faith in Christ Jesus: it was eaten only by Israelites, and such as became proselytes, as Christ, only by true believers; and if the household was too little, they were to join with their "neighbours"; which might typify the calling and bringing in of the Gentiles, when the middle wall of partition was broken down, Christ, his flesh and blood being common to both. The first passover was eaten in haste, with their loins girt, their shoes on, and staves in their hands, ready to depart from Egypt to Canaan's land; denoting the readiness of believers to every good work; having their feet shod with the preparation of the Gospel of peace; their loins girt about with truth, their lights burning, and they like men waiting for their Lord's coming; hasting unto the day of the Lord, being earnestly, desirous of being absent from the body, that they might be present with him: in a word, the receiving of the blood of the passover lamb into a bason, sprinkling it on the lintel, and two side posts of the doors of the houses, in which they ate it, which the Lord seeing passed over those houses, when he passed through Egypt to destroy the firstborn, whence it has its name of the passover, were very significative of the blood of sprinkling, even the blood of Christ upon the hearts and consciences of believers; whereby they are secured from avenging justice, from the curse and condemnation of the law, and from wrath to come, and shall never be hurt of the second death. Thus Christ is our antitypical passover, who was sacrificed, whose body and soul were offered as an offering and sacrifice unto God for us, that he might be proper food for our faith; and also in our room and stead, to make satisfaction to divine justice for all our sins and transgressions.

This was first fulfilled in Syria; for "the disciples were called Christians at Antioch," when Paul and Peter were laying the foundations of the Church. Lay aside, therefore, the evil, the old, the corrupt leaven, and be ye changed into the new leaven of grace.

Wherefore also Plato says, in the second book of the Republic, "It is those that sacrifice not a sow, but some great and difficult sacrifice," who ought to inquire respecting God. And the apostle writes, "Christ our passover was sacrificed for us;"-a sacrifice hard to procure, in truth, the Son of God consecrated for us.

Which prediction was thus also fulfilled, that "on the first day of unleavened bread" you slew Christ; and (that the prophecies might be fulfilled) the day hasted to make an "eventide,"-that is, to cause darkness, which was made at mid-day; and thus "your festive days God converted into grief, and your canticles into lamentation.

It does not matter that he also said, "For the destruction of the flesh, that the spirit may be saved in the day of the Lord," since both in the destruction of the flesh and in the saving of the spirit there is, on His part, judicial process; and when he bade "the wicked person be put away from the midst of them," he only mentioned what is a very frequently recurring sentence of the Creator. "Purge out the old leaven, that ye may be a new lump, as ye are unleavened." The unleavened bread was therefore, in the Creator's ordinance, a figure of us (Christians).

The unleavened bread was therefore, in the Creator's ordinance, a figure of us (Christians). "For even Christ our passover is sacrificed for us." But why is Christ our passover, if the passover be not a type of Christ, in the similitude of the blood which saves, and of the Lamb, which is Christ? Why does (the apostle) clothe us and Christ with symbols of the Creator's solemn rites, unless they had relation to ourselves? When, again, he warns us against fornication, he reveals the resurrection of the flesh.

For in what respect, he says, would the one tittle require any substance such as leaven (derived) from without for the Lord's Passover, the eternal feast, which is given for generation upon generation?. In other respects, however, these consent to all the traditions delivered to the Church by the Apostles. To have remodelled the old man. In the Passover season, so as to exhibit Himself as one destined to be sacrificed like a sheep, and to prove Himself the true Paschal-lamb, even as the apostle says, "Even Christ "who is God, "our passover was sacrificed for us."

The voice of the warning apostle is, "Purge out the old leaven, that ye may be a new lump, as ye are unleavened; for even Christ our passover is sacrificed. Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth." But are sincerity and truth preserved, when what is sincere is polluted by adulterous colours, and what is true is changed into a lie by the deceitful dyes of medicaments? Your Lord says, "Thou canst not make one hair white or black; " and you, in order to overcome the word of your Lord, will be more mighty than He, and stain your hair with a daring endeavour and with profane contempt. With evil presage of the future, you make a beginning to yourself already of flame-coloured hair; and sin (oh, wickedness!) with your head-that is, with the nobler part of your body! And although it is written of the Lord, "His head and His hair were white like wool or snow," you curse that whiteness and hate that hoariness which is like to the Lord's head.

That he who has attained to trust, having put off the former man, ought to regard only celestial and spiritual things, and to give no heed to the world which he has already renounced... Also in the same place: "Love not the world, neither the things that are in the world. If any man loveth the world, the love of the Father is not in him. Because everything which is in the world is lust of the flesh, and lust of the eyes, and the ambition of this world, which is not of the Father, but of the lust of this world. And the world shall pass away with its lust. But he that doeth the will of God abideth for ever, even as God abideth for ever." Also in the first Epistle of Paul to the Corinthians: "Purge out the old leaven, that ye may be a new dough, as ye are unleavened. For also Christ our passover is sacrificed. Therefore let us celebrate the feast, not in the old leaven, nor in the leaven of malice and wickedness, but in the unleavened bread of sincerity and truth."

"Purge out the old leaven," that is, this evil one. Not that he speaketh concerning this one only; rather he glances at others with him. For, "the old leaven" is not fornication only, but also sin of every kind. And he said not, "purge," but "purge out;" "cleanse with accuracy so that there be not so much as a remnant nor a shadow of that sort." In saying then, "purge out," he signifies that there was still iniquity among them. But in saying, "that ye may be a new lump, even as ye are unleavened," he affirms and declares that not over very many was the wickedness prevailing. But though he saith, "as ye are unleavened," he means it not as a fact that all were clean, but as to what sort of people you ought to be. "For our Passover also hath been sacrificed for us, even Christ; wherefore let us keep the feast: not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth." So also Christ called His doctrine Leaven. And further he himself dwells upon the metaphor, reminding them of an ancient history, and of the Passover and unleavened bread, and of their blessings both then and now, and their punishments and their plagues. It is festival, therefore, the whole time in which we live. For though he said, "Let us keep the feast," not with a view to the presence of the Passover or of Pentecost did he say it; but as pointing out that the whole of time is a festival unto Christians, because of the excellency of the good things which have been given. For what hath not come to pass that is good? The Son of God was made man for thee; He freed thee from death; and called thee to a kingdom. Thou therefore who hast obtained and art still obtaining such things, how can it be less than thy duty to "keep the feast" all thy life? Let no one then be downcast about poverty, and disease, and craft of enemies. For it is a festival, even the whole of our time. So that by means of this example also he mightily drives the fornicator out of the Church. For, saith he, so far from his presence profiting, he even doth harm, injuring the common estate of the body. For one knows not whence is the evil savor while the corrupt part is concealed, and so one imputes it to the whole. Wherefore he urges upon them strongly to "purge out the leaven, that ye may be," saith he, "a new lump, even as ye are unleavened." "For our Passover hath been sacrificed for us even Christ." He said not, hath died, but more in point to the subject in hand, "hath been sacrificed." Seek not then unleavened bread of this kind, since neither hast thou a lamb of the same kind. Seek not leaven of this description, seeing that thine unleavened bread is not such as this. Thus, in the case of material leaven, the unleavened might become leavened, but never the reverse; whereas here there is a chance of the direct contrary occurring. This however he has not plainly declared: and observe his good sense. In the former Epistle he gives the fornicator no hope of return, but orders that his whole life should be spent in repentance, lest he should make him less energetic through the promise. For he said not, "Deliver him up to Satan," that having repented he might be commended again unto the Church. But what saith he? "That he may be saved in the last day." For he conducts him on unto that time in order to make him full of anxiety. And what favors he intended him after the repentance, he reveals not, imitating his own Master. For as God saith, "Yet three days, and Nineveh shall be overthrown," and added not, "but if she repent she shall be saved:" so also he did not say here, "But if he repent worthily, we will 'confirm our love towards him.'" But he waits for him to do the work that so he may then receive the favor. For if he had said this at the beginning he might have set him free from the fear. Wherefore he not only does not so, but by the instance of leaven allows him not even a hope of return, but reserves him unto that day: "Purge out (so he says) the old leaven;" and, "let us not keep the feast with old leaven." But as soon as he had repented, he brought him in again with all earnestness. But why does he call it "old?" Either because our former life was of this sort, or because that which is old is "ready to vanish away," and is unsavory and foul; which is the nature of sin.

The old leaven has a double meaning here. On the one hand, it refers to false teaching, just as Jesus warned his disciples to beware the leaven of the Pharisees. On the other hand, it also refers to the sin of fornication being dealt with here. Paul teaches that the passover is the sacrifice, and not the exodus, as some people think. The sacrifice comes first, and then it is possible to make the transition from the old life to the new. For this reason it is the cross that is the saving reality signified by the passover in the Old Testament.

Let its name be inquired into more carefully. Let the excellent preacher be consulted. Let us see what he declares concerning the estimation of Him. For he says: "For Christ our Passover has been sacrificed." If therefore Christ is the Passover, we must consider what the law says about the Passover, so that we may investigate more carefully whether these things seem to have been said about Christ.

Purge out therefore this fornicator, or rather, drive out all other wicked persons as well (for by "old leaven" he means every kind of evil). In the Greek text it does not simply say "cleanse" (καθάρατε), but "purge out" (ἐκκαθάρατε), that is, cleanse completely, that you may be a new lump, having no admixture of evil. "Since you are unleavened," instead of: as you ought to be unleavened, that is, free from the old evil, which upon repentance proves to be both sour and bitter.

Having mentioned the unleavened breads, the azymes, which were eaten as food at Pascha, and having explained allegorically what the unleavened breads signify, namely a life free from evil, he now allegorically explains Pascha itself and says that our Pascha is Christ, slain for us. Therefore, we must take care concerning the unleavened breads, that is, a life pure from all evil.

Then when he says, Cleanse out the old leaven, he shows what should be done in the future: first he presents the teaching; secondly, he assigns reason (v.7). He says, therefore: Because a little leaven corrupts the whole lump, cleanse out the old leaven, i.e., cleanse yourselves by casting out from your midst the old leaven, i.e., the fornicator who returned to the old state of former corruption by sinning: "You are growing old in a foreign country, you are defiled with the dead" (Bar 3:10). And this is what he says, because by cutting off one sinner the whole group is cleansed; hence when Judas left the Lord said: "Now is the Son of Man glorified" (Jn 13:31). By the old leaven can also be understood the old error: "The old error is passed away" (Is 26:3), or even the corruption of original sin: "Seeing that you have put off the old nature with its practices" (Col 3:9), for a man is cleansed by removing them. Secondly, he mentions the effect of this cleansing, saying: that you may be a new lump. Here lump means a mixture of water and new flour, before leaven is mixed with it. Therefore, once the leaven, i.e., the sinner or sin, is removed from the faithful, they become as it were a new lump, renewed in purity: "Your youth is renewed like the eagle's" (Ps 103:5); "Be renewed in the spirit of your minds" (Eph 4:23). Thirdly, he mentions the form of cleansing should take when he says: as you really are unleavened, i.e., without the leaven of sin. In this sense the Lord says: "Beware of the leaven of the Pharisees and Sadducees" (Matt 16:6). Then when he says, For Christ our paschal lamb [pasch] has been sacrificed, he assigns the reason for what he had said, namely, why the faithful should be unleavened and it is taken from the mystery of Christ's passion. First, therefore, he mentions the mystery; secondly, he concludes to his point (v. 8). As to the first it should be noted that the most excellent sacrament of the Old Law was the paschal lamb which, as was commanded in Ex (c. 11), was sacrificed by the whole multitude of the children of Israel in commemoration of the event in which the angel striking the first born in Egypt passed by the homes of the Jews, whose posts were smeared with the blood of a lamb. The word "pasch" is derived from this event: "It is the Lord's Passover" (Ex 12:11). It was in virtue of the blessing that the people passed over the Red Sea (Ex 24:15ff). But this lamb was a figure of the innocent Christ, of Whom it is said: "Behold the Lamb of God" (Jn 1:36). Therefore, just as that lamb was slain by the children of Israel in order that God's people be delivered from the avenging angel and after being freed from the slavery under the Egyptians, pass over the Red Sea, so Christ was slain by the children of Israel, in order that God's people be delivered from the attacks of the devil by His blood and from the slavery of sin by baptism, as though by the Red Sea. Now that lamb was called the pasch of the Jews, because it was immolated as a sign of the passing; hence the disciples ask: "Where do you wish us to prepare for you to eat the pasch?" (Matt 26:17), i.e., the paschal lamb. Therefore, the Apostle says: You ought to be unleavened, for, i.e., because as the pasch of the old people was the sacrificed lamb, so our pasch, i.e., of the new people, is the sacrificed Christ. His immolation deserves the name pasch both by reason of what the word means in Hebrew, namely, passage, and what it means in Greek, namely, "passion": for Christ passed from this world to the Father by means of the passion, in which He was sacrificed (Jn 13:1).

Account of the incestuous person, or of him who had married his father's wife, Co1 5:1. The apostle reproves the Corinthians for their carelessness in this matter, and orders them to excommunicate the transgressor, Co1 5:2-5. They are reprehended for their glorying, while such scandals were among them, Co1 5:6. They must purge out the old leaven, that they may properly celebrate the Christian passover, Co1 5:7-9. They must not associate with any who, professing the Christian religion, were guilty of any scandalous vice, and must put away from them every evil person, Co1 5:10-13.

Purge out therefore the old leaven - As it is the custom of the Jews previously to the passover to search their houses in the most diligent manner for the old leaven, and throw it out, sweeping every part clean; so act with this incestuous person. I have already shown with what care the Jews purged their houses from all leaven previously to the passover; see the note on Exo 12:8-19 (note), and on the term passover, and Christ as represented by this ancient Jewish sacrifice; see on Exo 12:27 (note), and my Discourse on the Nature and Design of the Eucharist.

THE INCESTUOUS PERSON AT CORINTH: THE CORINTHIANS REPROVED FOR CONNIVANCE, AND WARNED TO PURGE OUT THE BAD LEAVEN. QUALIFICATION OF HIS FORMER COMMAND AS TO ASSOCIATION WITH SINNERS OF THE WORLD. (Co1 5:1-13) commonly--rather, "actually" [ALFORD]. Absolutely [BENGEL]. "It is reported," implies, that the Corinthians, though they "wrote" (Co1 7:1) to Paul on other points, gave him no information on those things which bore against themselves. These latter matters reached the apostle indirectly (Co1 1:11). so much as named--The oldest manuscripts and authorities omit "named": "Fornication of such a gross kind as (exists) not even among the heathen, so that one (of you) hath (in concubinage) his father's wife," that is, his stepmother, while his father is still alive (Co2 7:12; compare Lev 18:8). She was perhaps a heathen, for which reason he does not direct his rebuke against her (compare Co1 5:12-13). ALFORD thinks "have" means have in marriage: but the connection is called "fornication," and neither Christian nor Gentile law would have sanctioned such a marriage, however Corinth's notorious profligacy might wink at the concubinage.

old leaven--The remnant of the "old" (Eph 4:22-24) heathenish and natural corruption. The image is taken from the extreme care of the Jews in searching every corner of their houses, and "purging out" every particle of leaven from the time of killing the lamb before the Passover (Deu 16:3-4). So Christians are continually to search and purify their hearts (Psa 139:23-24). as ye are unleavened--normally, and as far as your Christian calling is concerned: free from the leaven of sin and death (Co1 6:11). Paul often grounds exhortations on the assumption of Christian professors' normal state as realized (Rom 6:3-4) [ALFORD]. Regarding the Corinthian Church as the Passover "unleavened lump" or mass, he entreats them to correspond in fact with this their normal state. "For Christ our Passover (Exo 12:5-11, Exo 12:21-23; Joh 1:29) has been (English Version, "is") sacrificed for us"; that is, as the Jews began the days of unleavened bread with the slaying of the Passover lamb, so, Christ our Passover having been already slain, let there be no leaven of evil in you who are the "unleavened lump." Doubtless he alludes to the Passover which had been two or three weeks before kept by the Jewish Christians (Co1 16:8): the Gentile Christians probably also refraining from leavened bread at the love-feasts. Thus the Jewish Passover naturally gave place to our Christian Easter. The time however, of keeping feast (metaphorical; that is, leading the Christian life of joy in Christ's finished work, compare Pro 15:15) among us Christians, corresponding to the Jewish Passover, is not limited, as the latter, to one season, but is ALL our time; for the transcendent benefits of the once-for-all completed sacrifice of our Passover Lamb extends to all the time of our lives and of this Christian dispensation; in no part of our time is the leaven of evil to be admitted. For even--an additional reason, besides that in Co1 5:6, and a more cogent one for purging out every leaven of evil; namely, that Christ has been already sacrificed, whereas the old leaven is yet unremoved, which ought to have been long ago purged out.
